Hope everything clears for your trip. Sorry to hear about that Harley 5 speed. They are usually pretty reliable, What went wrong.

No clear cut reason yet. When I had the sidecar on that one I beat it hard. Was known to fly the car for miles at a time. It is possible starved for lube. When it failed it tore the insides up.

I decided to have them replace everything inside. All Andrews gear set going in. Should have it back soon. Another reason I did not do it myself was the govern shut down HD for retail sales and restricted service. The was a Que for me to send them some work. Amazing Bicycle shops that sell E bike had no restriction on them. But Governor stuck it to HD dealers.

Regardless of the cost there was never any doubt , it would be repaired . To many memories attached to it.
